Shrink Discs
Introduction Keyless shaft-hub locking devices have been the cornerstone of the RINGFEDER®. For over 90 years, our product offering of in-ternal clamping and external clamping locking devices and global support has been unparalleled in the industry.
CharacteristicsShrink discs are the modern method for creating a mechanical shrink fit. The shrink disc consists of either one or two thrust rings with tapered bores and a mating tapered inner ring. By tightening locking screws the thrust rings are drawn together compressing the inner ring and applying pressure to the outside of the hub clamping it to the shaft. Thus the shrink disc is not in the load path. The torque can be transferred in a force-locking manner on the joining surface between the shaft and the hub without an intermediate element. This creates an optimum fit (shrink fit) for highly stressed shaft-hub connections. Before now the optimum fit needed to be produced through complex calculation, the smallest production tolerances and considerable effort during assembly and dismantling. Problems also occur during any necessary repairs (exchangeability, setting and/or centring, etc.). No other kind of shaft-hub connection has even close to these good features with regard to permanent rotational stability and has such excellent concentricity.
Unlimited range of applications – RINGFEDER® Shrink Disc connections are suitable for securing all types of hubs onto shafts and axles. Replacing traditional shrink fits, keys and polygon connections, splined shafts etc. So cog wheels and sprockets, levers, lifters, cam discs, pulleys or brake discs, balance wheels, couplings, slip on gear mechanisms, flanges, pulley wheels and rotors can be attached absolutely reliable.
Clearances considered for the calculation of the function values

2-part
Two-part shrink discs by RINGFEDER® are characterised by an extremely flat single cone and transfer the necessary torque in a similar way to a taper interference fit. The screws on the shrink discs can be tightened without using a torque wrench and therefore the discs can be mounted quickly and easily. The transferred torque is thus ensured via route-controlled assembly.
3-part
Three-part RINGFEDER® shrink discs are characterised by a steep double cone and transfer the required torque in a similar way to a taper interference fit. In contrast to this, however, the RINGFEDER® shrink discs can be simply and quickly assem-bled and disassembled. The shrink disc itself is not in the flow of forces. The distance between the flanges allows simple function checking. The function values can be adapted specifically to the individual customer and application requirements by varying the screw tightening torque.

Forged outer/pressure ring for the best stress distribution and thus ideal material use. Route controlled version with defined displace-ment path. Very good concentricity characteristics through contact by both rings in the clamped condition. The assembly can be carried out without a torque wrench. The clamping is thus independent of the screws’ friction system. The RINGFEDER® RfN 4161 series is replaced by the larger RINGFEDER® RfN 4181 from an internal diameter of 220 mm.

Table Clearance Technical information
Surface finishes: For shaft Ra ≤ 3,2 μm
Tolerances: For shaft see table
When using a hollow shaft instead of a solid shaft please contact our Engineering-Team.
Additional loads, e.g. tension, thrust or bending have to be taken into consideration accordingly
Function values: The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed conditions: The locking screws are lubricated using MoS2 (μtot= 0,1). The tapered cones are lubricated using MoS2 (μ = 0,05). The contact surfaces (dw) are in lightly oiled condition with coefficient of friction μ = 0,12. The hub and shaft materials have a modulus of elasticity of 210,000 N/mm2. (Lower values result in increased values for T and Fax with reduced tangential stress.) The maximum clearance S is being fully utilized. The shaft being used is solid, for hollow shaft applications the functional values will change. In cases where the assumed conditions do not apply then contact our Technical Department where we will be happy to assist you with your application.

Technical information
Surface finishes: For shaft Ra ≤ 3,2 μm
Tolerances: For shaft see table
When using a hollow shaft instead of a solid shaft please contact our Engineering-Team.
Additional loads, e.g. tension, thrust or bending have to be taken into consideration accordingly
Function values: The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed conditions: The locking screws are lubricated using MoS2 (μtot= 0,1). The tapered cones are lubricated using MoS2 (μ = 0,05). The contact surfaces (dw) are in lightly oiled condition with coefficient of friction μ = 0,12. The hub and shaft materials have a modulus of elasticity of 210,000 N/mm2. (Lower values result in increased values for T and Fax with reduced tangential stress.) The maximum clearance S is being fully utilized. The shaft being used is solid, for hollow shaft applications the functional values will change. In cases where the assumed conditions do not apply then contact our Technical Department where we will be happy to assist you with your application.

Explanation
d = Inner diameter
D = Outer diameter
dw = Solid shaft diameter
d1 = Pitch circle diameter
L = Overall length
L1 = Overall length (without screws)
L2 = Thrust ring width
L3 = Width of ring
LB = Width of the half Shrink Disc
TA = Max tightened torque of the clamping screws
T = Transmissible torque at given TA
Fax = Transmissible axial force
P = Hub surface pressure
σv = Equivalent stress in the hub
nSc = Quantity of screws
DG = Thread
Gw = Weight
Tmax = Max. transmissible torque
Ordering example
Technical information
Surface finishes: For shaft Ra ≤ 3,2 μm
Tolerances: For shaft see table
When using a hollow shaft instead of a solid shaft please contact our Engineering-Team.
Additional loads, e.g. tension, thrust or bending have to be taken into consideration accordingly
Function values: The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed conditions: The locking screws are lubricated using MoS2 (μtot= 0,1). The tapered cones are lubricated using MoS2 (μ = 0,05). The contact surfaces (dw) are in lightly oiled condition with coefficient of friction μ = 0,12. The hub and shaft materials have a modulus of elasticity of 210,000 N/mm2. (Lower values result in increased values for T and Fax with reduced tangential stress.) The maximum clearance S is being fully utilized. The shaft being used is solid, for hollow shaft applications the functional values will change. In cases where the assumed conditions do not apply then contact our Technical Department where we will be happy to assist you with your application.

LB = Width of the half Shrink Disc
TA = Max tightened torque of the clamping screws
T = Transmissible torque at given TA
Fax = Transmissible axial force
P = Hub surface pressure
σv = Equivalent stress in the hub
nSc = Quantity of screws
DG = Thread
Gw = Weight
Tmax = Max. transmissible torque
Ordering example
Technical information
Surface finishes: For shaft Ra ≤ 3,2 μm
Tolerances: For shaft see table
When using a hollow shaft instead of a solid shaft please contact our Engineering-Team.
Additional loads, e.g. tension, thrust or bending have to be taken into consideration accordingly
Function values: The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed conditions: The locking screws are lubricated using MoS2 (μtot= 0,1). The tapered cones are lubricated using MoS2 (μ = 0,05). The contact surfaces (dw) are in lightly oiled condition with coefficient of friction μ = 0,12. The hub and shaft materials have a modulus of elasticity of 210,000 N/mm2. (Lower values result in increased values for T and Fax with reduced tangential stress.) The maximum clearance S is being fully utilized. The shaft being used is solid, for hollow shaft applications the functional values will change. In cases where the assumed conditions do not apply then contact our Technical Department where we will be happy to assist you with your application.

Technical information
Surface finishes: For shaft Ra ≤ 3,2 μm
Tolerances: For shaft see table
When using a hollow shaft instead of a solid shaft please contact our Engineering-Team.
Hub with yield strength Rp0,2 ≥ 360 N/mm2
Additional loads, e.g. tension, thrust or bending have to be taken into consideration accordingly
Function values: The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed conditions: The locking screws are lubricated using MoS2 (μtot= 0,1). The tapered cones are lubricated using MoS2 (μ = 0,05). The contact surfaces (dw) are in lightly oiled condition with coefficient of friction μ = 0,12. The hub and shaft materials have a modulus of elasticity of 210,000 N/mm2. (Lower values result in increased values for T and Fax with reduced tangential stress.) The maximum clearance S is being fully utilized. The shaft being used is solid, for hollow shaft applications the functional values will change. In cases where the assumed conditions do not apply then contact our Technical Department where we will be happy to assist you with your application.

Technical information
Surface finishes: For shaft Ra ≤ 3,2 μm
Tolerances: For shaft see table
When using a hollow shaft instead of a solid shaft please contact our Engineering-Team.
Hub with yield strength Rp0,2 ≥ 360 N/mm2
Additional loads, e.g. tension, thrust or bending have to be taken into consideration accordingly
Function values: The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed conditions: The locking screws are lubricated using MoS2 (μtot= 0,1). The tapered cones are lubricated using MoS2 (μ = 0,05). The contact surfaces (dw) are in lightly oiled condition with coefficient of friction μ = 0,12. The hub and shaft materials have a modulus of elasticity of 210,000 N/mm2. (Lower values result in increased values for T and Fax with reduced tangential stress.) The maximum clearance S is being fully utilized. The shaft being used is solid, for hollow shaft applications the functional values will change. In cases where the assumed conditions do not apply then contact our Technical Department where we will be happy to assist you with your application.

Technical information
Surface finishes: For shaft Ra ≤ 3,2 μm
Tolerances: For shaft see table
When using a hollow shaft instead of a solid shaft please contact our Engineering-Team.
Additional loads, e.g. tension, thrust or bending have to be taken into consideration accordingly
Function values: The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed conditions: The locking screws are lubricated using MoS2 (μtot= 0,1). The tapered cones are lubricated using MoS2 (μ = 0,05). The contact surfaces (dw) are in lightly oiled condition with coefficient of friction μ = 0,12. The hub and shaft materials have a modulus of elasticity of 210,000 N/mm2. (Lower values result in increased values for T and Fax with reduced tangential stress.) The maximum clearance S is being fully utilized. The shaft being used is solid, for hollow shaft applications the functional values will change. In cases where the assumed conditions do not apply then contact our Technical Department where we will be happy to assist you with your application.
